TPS92601BQPWPRQ1 - Automotive Dual Channel Automotive Headlight LED Driver, HTSSOP-20

Model: TPS92601BQPWPRQ1

Package: HTSSOP-20

Type: Automotive LED Driver

Overview:

The TPS92601BQPWPRQ1 is a single and dual high side current LED driver. With full protection and diagnostic features, this family of devices is specifically targeted and ideally suited for automotive headlamps. At the bottom of each individual driver is a peak current mode boost controller. Each controller consists of two independent feedback loops, a current feedback loop with a high-side current sense tap, and a voltage feedback loop with an external resistor divider network.

TPS92601BQPWPRQ1 - Product Features:

Input Voltage: 4V - 40V (Absolute Maximum 45V)

Output Voltage: 4V - 75V (80V absolute maximum)

Fixed frequency current mode controller with integrated ramp compensation

Two regulator loops, constant current output and constant voltage output (per channel)

High side current sense:

- 150mV or 300mV sense voltage (EEPROM option)

- ±6mV offset (for approximately 4% or 2% LED current accuracy)

Output Voltage Sense, Internal Voltage Reference: 2.2V ±5

Integrated low-side NMOS-FET driver: 0.7A typical peak gate drive current

Frequency synchronisation

Supports pulse width modulation (PWM) dimming and analogue dimming

Diagnostics:

- High-side current (LED current) available as an analogue output

- Open LED and short-to-ground detection

- Short-circuit output protection

Internal undervoltage and overvoltage blocking

High Brightness LED Design

• 1.Is the inventory and price seen on the platform accurate?

  A: all online goods on the shelves can be ordered online, but considering the large liquidity of spot inventory, it is not possible to achieve 100% accuracy at present. In case of any abnormality, you can contact our company online and give the corresponding solution.

• 2.Are all our products genuine?

  A: our self-supporting products are from cooperative domestic and foreign original factories or authorized agents, and the source can be traced to ensure the original and authentic products.

• 3.Can you provide the qualification certificate of the original factory or agent?

  A: at present, our self-employed brands TI，ST，ADI，NXP，LATTICE，CYPRESS，INFINEON，XILINX and other first-line brands. Other channels are the original factory and agency channels. If necessary, we can communicate and confirm according to the specific brand and model.

• 4.Can I make an inquiry through the company's website?

  A: You can inquire through the website, or by phone and email.

• 5.When can I deliver the goods after placing an order? How long will it take to get there?

  A: the delivery date is marked in most commodity information. You can estimate the delivery time of the commodity according to the delivery date. The specific arrival time depends on the warehouse where the commodity is located and the logistics mode you choose.

• 6.Can the company issue an invoice?

  A: you can issue ordinary invoices for individual users or special VAT invoices for enterprise users.
